Thanks for reporting this. I’m not sure what is preventing the add-on from working on 2.0.
I see the maintenance of this add-on had been taken over by @mrstegeman from its original author, but Mike is no longer able to contribute.
I have filed an issue on the original repo, but I think it’s likely this add-on will need a new maintainer in order for it to be upgraded for use with 2.0.
In the meantime we should list it as working with maximum version 1.1.
The issue is with add-on compatibility, not 32-bit vs. 64-bit systems. The v.2.0 add-on needs a new maintainer to work with the updated software, which is why v1.1 still functions.
